 ****************************************************************************

   This include file defines some conditional defines to allow us to select
   the compiler/platform/target in a consequent way.

    OS_XXXX         The operating system used (XXXX may be one of:
                       DOS, OS2, Linux, Windows, Go32, FreeBSD,Linux)
    PPC_XXXX        The compiler used: BP, FPK, Virtual, Speed
    BIT_XX          The number of bits of the target platform: 16 or 32
    PROC_XXXX       The mode of the target processor (Real or Protected)
                    This shouldn't be used, except for i386 specific parts.
    ASM_XXXX        This is the assembler type: BP, ISO-ANSI, FPK
